The Angle of Attack (AOA) Configuration page is accessible only when an AOA input is enabled on the
LRU Configuration page (

Flight AOA Calibration procedure follows.
33.4.6.1
AOA Calibration (Performed In-flight)
Installations that include a GAP 26 and which have AOA enabled require that an AOA calibration be
performed to enable AOA functionality. The AOA calibration is used to determine the four AOA settings
shown in Figure 33-23. These calibrations must be done while in flight. The AOA Setup page
(
) on PFD 1 is used for the AOA cal procedure, and is accessed in normal mode (requires that
an AOA input is enabled on the LRU Configuration page, see
WARNING
AOA calibration involves flying the aircraft at low airspeeds and angles of attack at or near
the stall point. Do not perform AOA calibration until the aircraft's stall recovery
characteristics are well-understood. Before AOA calibration, ensure that the aircraft is
clear of all traffic and at a safe altitude for stall recovery.
